Abstract
Embodiments of golf club heads with a three-dimensional alignment member and methods to manufacture golf club heads are generally described herein. Other embodiments may be described and claimed.
Claims25
A golf club head, comprising:
- a face portion having a heel end and a toe end and including a top rail;
- and
- a three-dimensional alignment member having a first arcuate portion and a second arcuate portion, the first and second arcuate portions being based on a dimension of a golf ball, at least a portion of the three-dimensional alignment member centrally positioned between the heel end and the toe end, the three-dimensional alignment member including a first arc section associated with the first arcuate portion, a second arc section associated with the second arcuate portion, and a central portion having a straight section extending between the first arc section and the second arc section;
- wherein the first and second arcuate portions extend above the top rail, and
- wherein the first and second arcuate portions are convex relative to a vertical plane substantially parallel to the face portion.
2 more elements
A golf club head as defined in claim wherein the three-dimensional alignment member comprises a material associated with a specific gravity of less than 3.5 (g/cm).
A golf club head, comprising:
- a first body portion having a heel end and a toe end and made of a first material associated with a first density, the first body portion having a top rail extending in a direction from the heel end to the toe end;
- and
- a second body portion made of a second material associated with a second density, the second body portion having first arcuate portion and a second arcuate portion to form a visual alignment member based on a dimension of a golf ball, at least a portion of the first arcuate portion intersecting a plane substantially perpendicular to the top rail, and at least a portion of the second arcuate portion intersecting the plane,
- wherein the first body portion comprises a C-shaped configuration relative to an individual at an address position, and wherein the second body portion comprises a Y-shaped configuration relative to a golf ball at an address position;
- wherein the first and second arcuate portions extend above the top rail, and
- wherein the first density is greater than the second density.
3 more elements
A method comprising:
- providing a first body portion having a heel end and a toe end and made of a first material associated with a first density, the first body portion having a top rail extending in a direction from the heel end to the toe end;
- and
- providing a second body portion made of a second material associated with a second density, the second body portion having a first arcuate portion and a second arcuate portion to form a visual alignment member based on a dimension of a golf ball, at least a portion of the first arcuate portion intersecting a plane substantially perpendicular to the top rail, and at least a portion of the second arcuate portion intersecting the plane,
- providing a first arc section associated with the first arcuate portion;
- providing a second arc section associated with the second arcuate portion;
- providing a central portion having a straight section to connect the first arc section and the second arc section,
- wherein the first and second arcuate portions extend above the top rail, and
- wherein the first density is greater than the second density.
5 more elements
A golf club head, comprising:
- a first body portion having a heel end and a toe end and made of a first material associated with a first density, the first body portion having a top rail extending in a direction from the heel end to the toe end;
- and
- a second body portion made of a second material associated with a second density, the second body portion having a first arcuate portion and a second arcuate portion to form a visual alignment member based on a dimension of a golf ball, at least a portion of the first arcuate portion intersecting a plane substantially perpendicular to the top rail, and at least a portion of the second arcuate portion intersecting the plane,
- wherein the first body portion comprises a first arm portion, a second arm portion, and a face portion connecting the first arm portion and the second arm portion, and wherein the second body portion comprises a first leg portion extending from the second arcuate portion to the first arm portion, and a second leg portion extending from the second arcuate portion to the second arm portion;
- wherein the first and second arcuate portions extend above the top rail, and
- wherein the first density is greater than the second density.
3 more elements
A golf club head, comprising:
- a first body portion having a heel end and a toe end and made of a first material associated with a first density, the first body portion having a top rail extending in a direction from the heel end to the toe end;
- and
- a second body portion made of a second material associated with a second density, the second body portion having, a first arcuate portion and a second arcuate portion to form a visual alignment member based on a dimension of a golf ball, at least a portion of the first arcuate portion intersecting a plane substantially perpendicular to the top rail, and at least a portion of the second arcuate portion intersecting the plane,
- wherein the first body portion comprises a first arm portion and a second arm portion to form a contour having outward curving portions adjacent to an inward curving center portion, and wherein each of the outward curving portions is located at or proximate to an end of the first arm portion and the second arm portion,
- wherein the first and second arcuate portions extend above the rail, and
- wherein the first density is greater than the second density.
